Added (1). I'm studying so tried to study more than my eye wanted and it felt very tight and painful so I stopped.
Have I damaged it and how can I prevent damage? I have taken my right contact lens out.
Added (2). PS how do I prevent this overstraining happening again while studying please?
I would greatly appreciate any help and will pick a best answer. Thank you very much:).
